STORM-SASH-HOLDING DEVICE.

Specification of Letters Patent.

Patented Sept. *7, 1909.

Application filed April 3, 1909. SerialNo. 487,750.

To all whom it may concern:

Be it known that'I, WILLIAM R. HALLAM, a citizen of the United States,residing at Superior, in the county'of Douglas and State of Wisconsin,have invented certain new and useful Improvements in Storm-Sash-HoldingDevices, of which the following is a specification.

The present invention, While relating more particularly to means formaintaining a storm sash in diflerent positions, with respect to theframe on which it is mounted,

is not necessarily limited to such use, but

may be successfully employed in connection with relatively movablemembers of difierent kinds.

The primary object of the invention is to provide a simple article ofmanufacture, which can be readily applied by an unskilled person to themembers to be held, and will effectively maintain said members either incompletely closed or completelyopen position, or at differentintermediate points.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a perspective view of aportion of a storm sash and frame, showing the former in partially openposition, and held by the novel means. Fig. 2 is a similar view,illustrating the sash completely open. Fig. 3 is a vertical crosssectional view through the sash and frame when the former is in closedposition, and illustrating the holding means in side elevation. Fig. 4-is a vertical sectional view on the line 4t of Fig. 3. Fig. 5 is ahorizontal sectional view on the line 55 of Fig. 3. Fig. 6 is a detailsectional view through the pivotal connection between the links. Fig. 7is a face view of the inner sides of the two links at their pivotalconnection, showing the interfitt-ing teeth.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment disclosed, a bracket 8 is employed, which is securedto the frame or sill 9 of the window by screws 10 or other fasteners,and has an upstanding ear 11.

Another bracket 12 is in like manner se-' cured to the sash 13, byscrews or other fasteners 14. This bracket 12 also has an outstandingcar 15 and a curved lip 16, which constitutes a finger-piece.

Pivotally connected to the car 11 of the bracket 8, as shown at 16 is alink 17, and

pivotally connected at 15 to the ear 15 of the bracket 12, is anotherlink18. The link 17 can swing between a substantially horizontal and asubstantially vertical position, being stopped in the latter position bythe sharp corner 19 of said link abutting against the bracketS. Thelinks 17 and 18 are pivotally connected by a bolt 20 having a head 21 onone end and having a clamping wing nut 22 threaded on its other end. Thebolt is held against turning by a pin 23 carried by the link 17, andengaging in a notch 2-it formed in one side of the head 21. A spring 25is interposed between the link 17 and the head 21, and serves to urgethe adjacent ends of the links toward each other.' This spring, asshown, is substantially in the'form of a split ring, between the ends ofwhich passes the pin 23,'so that the spring is also held against turningby said pin (see Fig.

Surrounding'the bolt, and carried respectively bythe adjacent ends ofthe links 17 and 18, are interfitting teeth 26 that are disposedradially to said bolt.

The bracket 12 is provided: with an outstandingcurved spring latch 27,which may be held upon the bracket by any suitable means, as forinstance, the fasteners 14. This latch has on its outer or free endportion a tooth or lug 28, which is arranged to snappingly engage overthe outer edge of the link 17, when the links are located side by side,as shown in Figs. 3 and 5.

The operation of the structure is substantially as follows. When thesash is in closed condition, as illustrated in Figs. 2 and 3, the twolinks are disposed in substantially vertical relation, side by side, inwhich case, the tooth or lug 28 of the latch 27 will engage over theouter edge of the link 17, and con sequently said sash will be locked inits closed position. This locking action may be made even more secure bytightening the Wing nut 22 on the pivot bolt 20, in which case, theteeth will be positively maintained in their interfitting relation. Ifit is desired to open the sash, it is only necessary to loosen the nut22, and disengage the latch from the link, whereupon by pushingoutwardly the sash can swing freely, the links 17 and 18,

swinging to different angular relations.

I 25 serves to yieldingly urge saidteeth into interfitting relation.Consequently the links will remain in the different angular relations inwhich they may be placed, or they may be positively locked by tighteningthe nut 22. The outward limit of movementof the sash is determined bythe length of the links, and

as shown in Fig. 2, when said links are alined, the sash of coursecannot move farther. The said .llnks may be now posi- :tively locked bytightening the nut.

It Will be evident that this device is simple, 1s veffectlve andconstitutes means for securely maintalning a storm sash or other devicein different positions with respect :to the frame of the window.

From the foregoing, it .is thought that the construction,operation andmany advantages .of the herein descrlbed invention Wlll be apparent tothose skilled 1n the art, without further description, and it will beunderstood that varlous changesin the s1ze,.shape, proportion and minordetalls of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

In connection with the .mlnor details of construction may be mentionedthe feature of providing the adjoining pivotally connected ends of thelinks 17 and 18 with laterally deflected corner portions 8 producingopposing stop shoulders. The said opposing shoulders s of the links 17and 18 .provide what may be termed a stop joint to prevent theappliance, when open, from jackknifing or shutting up beyond ahorizontal V 1. A device for holding two relatively movable members indifferent relativeposr tions, comprising pivotally connected links,brackets to which the ,lin'ks'are pivoted, and holding latch carried byone bracket and detachably engaging the link that is .pivoted to theother bracket to holdthe linksagainst relative movement.

2. A device for holding two relatively movable members in difierentrelative positions, comprising brackets, and means for securing the sameto the members to beheld, links pivoted to the brackets, a .pivot bolt'connecting the links, a spring, and a clamp ing nut on the .pivot boltforurging the links toward each other, inter-fitting teeth carried bythe links and disposed around the pivot bolts, a spring latch secured toone bracket and having ,a tooth that engages over the link that ispivoted to the other bracket,

when the links are located side by side, and

.a handle lip formed upon the bracket carrying the latch.

In testlmony whereof I hereunto afiiX. my slgnature 1n the presence oftwo wltnesses.
